METHOD OF FORMING WATCH-PENDANTS.

Specification of Letters Patent.

Patented Apr. 25, T9116.

Application filed Uctober 26, 1915. Serial No. 57,926.

To all whom it may concern:

Be it known. that we, BERNARD LEVY and WILLIAM B. CLARK, citizens of the United States, and residents of Riverside, county of Burlington, and State of New Jersey, have made and invented a certain new and Improved Method of Forming VVatch-Pendants, of which the following is a specification.

This invention relates to an improved method of forming watch pendants, and relates in particular to the formation of watch pendants having a filled metal body.

It has been found that a watch pendant having integral trunnions projecting therefrom, possesses many structural advantages, the same being fully outlined in our copending application Serial Number 34,587, filed June 27, 1915, and the present invention relates to a method for economically producing watch pendants of this character.

Other objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing from the spirit thereof.

The preferred embodiment of our inven tion is disclosed in the accompanying drawings, wherein Figure 1 illustrates the filled metal stock from which the pendants are formed; Fig. 2 illustrates the pendant in its first stage of formation; Fig. 3 discloses the body of the pendant shaped to its final form, and prior to the securement of the bow thereto; Fig. 4L is a view in elevation of the completed bow and pendant; and Fig. 5 is an enlarged view in section of the connection between the body of the pendant and the bow.

Referring specifically to the several views, the rod 10, formed with the base metal 11 and precious metal coating 12, is cut into lengths slightly in excess of the length of the finished body of the pendant. A length of this stock, which forms or constitutes a filled metal blank, is placed within suitable dies (not shown), and is subjected to longitudinal or endwise compression. Cylindrical trunnions 13 are forced from the sides of the blank, and occupy a plane perpendicular to the longitudinal axis thereof.

The cylindrical trunnions, being forced from the sides of the blank, are completely covered by the precious metal 12, which precious metal extends completely around the ends of the trunnions which are exposed to view. The blank is then subjected to crosswise or transverse compression, and is cut and shaped so as to harmonize with the style of watch case to which it is to be attached. A bow 14, preferably of filled metal stock, is provided with the alined openings 15 extending through the ends thereof, which openings define hubs 16. The ends of the how are sprung over the integral trunnions 13 and effect a swinging joint therewith. The trunnions are slightly longer than the hubs, so as to protrude therebeyond, which protruding extremities are spun or so treated as to form enlarged heads 20, thus effecting a rigid and permanent securement between the pendant and how. The outer extremities of the hubs are preferably counterbored so that the enlarged heads 20 of the trunnions may seat therein, and thus present a neat and sightly appearance.

The headed ends of the trunnions which are exposed to view are completely covered by precious metal, and so present the desired appearance.

What we claim is The method of forming a watch pendant consisting in subjecting to endwise compression a rod-like filled metal blank, the length of which is in excess of the length the completed pendant is to possess, and forcing from the sides of said blank a body with cylindrical trunnions projecting therefrom, said body and cylindrical trunnions possessing a complete covering of precious metal, mounting the hubs of a bow upon said trunnions and subjecting the said trunnions to endwise compression, forming heads upon said trunnions extending over the hubs of the bow and provided with a complete covering of precious metal.

Signed at Riverside, county of Burlington, and State of New Jersey, this 22nd day of October, 1915.

BERNARD LEVY. WILLIAM B. CLARK.
